IMPROVEMENT lN COMBINED PETTICOAT-PIPE AND FEED-WATER HEATER.

Specification forming part of Letters Patent No. 184,682, dated November21, 1876; application filed August 29, 1876.

clare the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings and to the letters ofreference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof a combined petticoat-pipe and feed-water heater for locomotives, aswill be hereinafter more fully set forth.

In order to enable others skilled in the artto which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichthe figure represents a vertical section of my invention, showing bydotted lines its position under the smoke-stack of the locomotive.

A represents the outer cylindrical shell, and B the inner shell orpetticoat-pipe. This inner shell is made cylindrical from the upper enddownward for a suitable distance, and the lower end is made conical, sothat the lower edges of the two shells will be united together, asshown, while the upper ends of the two shells are connected'by anannular head, 0. By this construction of the device a central steam andsmoke space, a, is formed, and between the sheels is the water spaee b.The petticoat-pipe also forms the inner wall of the feed-water heater. Dis the inlet for the water, and E is the outlet for the same. ,At thebottom of the heater is a circumferential band, Gr, made adjustable upand down, and held by means of bolts passing through vertical slots inthe baud. d d are simply lugs to keep the heater in its place in thesmoke-arch of the locomotive. The pipes D E should be connected with theheater by union couplings, so that the heater can be taken out of thesmoke-arch at any time by loosening said couplings for the purpose ofgaining access to the fines or otherwise, as may be required. The heateris placed in the position, as shown in the drawing, directly over theexhauststeam pipes E E, whereby it performs the combined function of apetticoat-pipe and a feed-water heater. v

The objectof 'the invention is to utilize the waste heat of combustionand exhaust steam to heat the water before entering the boiler. It is noimpediment to the draft, and by means of the adjustable band G at thebottom it will give more or less draft, as may be required. For the,purpose of cleaning the heater there are'plu gs h h in the head 0, whichcan readily be taken out and replaced again.

I do not broadly claim a water-heater within the smoke box or chimney ofa boiler.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- The petticoat pipe B,surrounded by wall A, forming water-chamber b, in combination witheduction and induction pipes D E, and the adjustable band G, allconstructed substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have, hereunto set my handthis 4th day of August, 1876.

CHARLES E. WINANS.
